at present , The engine is still in its infancy , But this solution has several technical advantages . One of the weaknesses of hydrogen is , It is possible to catch fire at a hot spot in the cylinder . According to introducing , There are no hot spots in the Wankel engine , Because it uses a rotor , Not the piston , So it's very suitable for burning hydrogen .

Of course , This is not unprecedented . Mazda is in 2000 Age testing and even renting experimental RX-8, Its engine can use gasoline or hydrogen . however , The system occupies the whole trunk , Heavy near 200 pounds . This engine is even used in some test Mazda5 Mini vans . lately , Toyota Made a Corolla Parameters picture ) Endurance Sports-Car , Powered by a hydrogen burning turbocharged three cylinder engine .

at present , There is no information on which model the new rotor engine will be used . One possibility is RX-Vision Concept coupe , This model was launched this year 8 May appear in the trademark application , It may be listed as a hybrid vehicle with a pair of in wheel motors . If it looks close 2015 Concept car , without doubt , Fans will welcome it as RX-8 Successor .

An anonymous person in charge of Mazda said :“ If we decide to do this , Its prototype may be completed within three years . The most likely is a system combined with an electric turbine .” Prototyping is relatively easy ; Develop a compelling business case , It's much more difficult . Final , Whether the project is licensed for production , It depends on the development cost , And the number of people buying vehicles .
